There have been some problems with the wiring harness from from the top of the liftgate into the roof where it flexes and bends every time the liftgate is opened and closed. The ground wire breaks which will disable the RKE (the module is in the liftgate) with the wiper, and the power lock mechanism. The license plate lights will be dead too when that ground is open. Everything electrical in the liftgate shares a common ground.

I had this problem too
I repaired like this for .10 $
Look at the backdoor
inside you have a motor ( black )with a little white arm
at the end of this arm, a part like a black pill
slide out of his case, this is why the keyless fail.
I did a little hole
and place an aluminium plate over this black part
to keep it in
buy a bold size 2 or 3
with a lock nut
excuse my poor english

Interesting. Good illustation btw...
So that arm comes out of the motor where it should nomally be connected, and then won't unlock the latch mechanism? That arm goes over to the latch that's operated by the outside handle?

all this system goes with outside handle
it's there to move some pins to stop the handle
and windows's button to move !
if you look inside the car ( lift the backdoor )
remove the little round plastic cover at the bottom
of the backdoor
you will see the white part of the motor
( electric connexions )
at the right end of the white arm you have this little black piece how is pushing to do rotate (x - y axe )a grey part
usualy it stay well, but sometime the white arm
can't because the black piece slide so easily.
remove a bolt under the belt how close the door
remove the inside cover of the backdoor
and 4 bolts under the door as shown in first image
do a little hole .... red ......in the yellow part
you have the place to do a hole whitout touching at the arm
do a aluminium plate..........green
with same holes
buy a little bolt ( sz 2 or 3 ) with lock nut
and install like before the last image
excuse my english
and I hope you will understand
but the garage asked me 400.oo$ to repair the keyless system
with perseverance it's costed me a bolt and nut
and free time

That's very nice! Did you create the graphics yourself? I'm impressed.
Consider writing up a Guide
SUVs and Smart Shopper
